After you enable command authorization, you need to perform the following configuration to make the
function take effect:
• Create a HWTACACS scheme, and specify the IP address of the authorization server and other
authorization parameters. For more information, see the Security Configuration Guide.
• Reference the created HWTACACS scheme in the ISP domain. For more information, see the
Security Configuration Guide.
After you enable command accounting, you need to perform the following configuration to make the
function take effect:
• Create a HWTACACS scheme, and specify the IP address of the accounting server and other
accounting parameters. For more information, see the Security Configuration Guide.
• Reference the created HWTACACS scheme in the ISP domain. For more information, see the
Security Configuration Guide.
When users adopt the scheme mode to log in to the device, the level of the commands that the users can
access depends on the user privilege level defined in the AAA scheme.
• When the AAA scheme is local, the user privilege level is defined by the authorization-attribute
level level command.
• When the AAA scheme is RADIUS or HWTACACS, the user privilege level is configured on the
RADIUS or HWTACACS server.
For more information about AAA, RADIUS, and HWTACACS, see the Security Configuration Guide.
When you log in to the device through Telnet again:
• You are required to enter the login username and password. A prompt such as <HP> appears after
you enter the correct username (for example, admin) and password and press Enter, as shown in
Figure 15.
• After you enter the correct username and password, if the device prompts you to enter another
password of the specified type, you will be authenticated for the second time. In other words, to
pass authentication, you must enter a correct password as prompted.
• If “All user interfaces are used, please try later!” is displayed, it means the current login users
exceed the maximum number. Please try later.
